Kind Code:
A1
Abstract:
A detection device according to an embodiment of the present application detects the presence or absence of a workpiece adhered to the inner wall of a drum of a mill for crushing minerals. This detection device stores an initial torque detected at a preset initial rotation angle, calculates a maximum torque on the basis of the initial torque, the initial rotation angle, and a rotation angle greater than the initial rotation angle, calculates the ratio of the torque at the rotation angle divided by the maximum torque, compares the ratio to a preset threshold, and determines that there is a workpiece adhered to the inner wall of the drum if the ratio is equal to or greater than the threshold.
